Please add scaling and latch/toggle to each CC
What do you mean by that?
Scaling = Similar to how scaling works in widgets - the ability to set max and min values and/or invert them also
Latch = like a switch so when you press a pedal it locks to max, and then you press it again to lock to min
Momentary = typically the way it already works. pedal down = max, pedal up = min
OK, just to be sure I understand you correctly:
You are talking about the Midi Filter Plugin?
By the way, that all can already be done with scripting or using widgets
Associate an incoming CC number with a widget and then scale the widget. The point is to use host automation to control plugin parameter and not control those parameters using MIDI
